نکته سوم: have to – has to

١- اجبار در زمان حال را بيان مي کند.

٢- بعد از آن فعل به صورت ساده بيان مي شود.

1- I have to ……… an appointment with the dentist.

a) makes          b) make *         c) to make         d) making

بعد از  has to و have to فعل بايد به شکل ساده بيايد.

2- Does she ……… speak French in her job?

a) has to        b) had to           c) have to *     d) can

ابتدا ذکر مي کنيم گزينه a درست است اما بايد دقت کنيم که وقتي که has to و have to با فعل کمکي سؤال مي شود، فعلهاي کمکي اين دو فعل do،does هستند و يادمان باشد وقتي has to با فعل کمکي does سئوالي شود، فعل تبديل به have to مي شود.

3- She has to ……… her lesson carefully.

a) study *           b) studied        c) to study         d) studying

4- Does john ……..help his mother at home?

a) have to *        b) has to      c) had to       d) can

چون جمله با فعل does سؤالي شده has to تبديل مي شود.

نکته چهارم: had to مجبور بودن

١- had to اجبار در زمان گذشته را بيان مي کند.

٢- گذشته have to و has to، had to مي باشد.

٣- بعد از had to بايد شکل ساده فعل قرار بگيرد.

1- They didn’t know the address. They ……… ask a policeman.

a) have to          b) can            c) had to *       d) can

چون اتفاق در زمان گذشته است از فعل کمکي had to استفاده مي کنيم.

2- Reza was late for class. He ……..see the teacher.

چون was گذشته است بنابراين had to صحيح مي باشد.
